Many Times, I have seen forums topics about the evil twin 4x4. I, am a cuber, and do some modding. Now my project is to make a 4x4 evil twin. I am going to use VietCuber's Tutorial, Since I will use mini dianshengs, from c4u, anyone know a better tutorial? Another thing, how do I make the cubes smoother, would a plastic weld be good to hold the plastic pieces?
Also does anyone know how to fill it, not cap, but fill with a white substance same as the cube, so you couldnt tell it was filled, and so it wouldn't be smelly. Thanks A lot Comment!!
